Perrier,
I see that several others have beat me to the punch on the digipot issues.
So I
think I'll sit this one out and just try to learn.

Perrier,
In answer to your 2nd question, I am unaware of any oscillator technology
for which
tuning the actual oscillator frequency has either (much less both) of
instant full
response or absolutely zero effect on its frequency drift trend
afterwards.
Instantaneous full response is generally not
Yo Bubba Dudes!,
Previous posts mentioned wiper noise and stability of a mechanical pots after
tweaking.
My questions are:
Do digital pots after setting have wiper noise?
When making fine tuning tweaks to the EFC of an OCXO, can one move it to its
*dead on* setting right away or is there some
